Nematode?? Under Microscope?

[tpirovol]

Is this a nematode and are they ok?? Found it in my filter floss along with a few others while checking for dino’s

There are likely hundreds of types microorganisms in every established reef tank that we don't know are there and which either help or don't cause a problem, and the chance of finding one in a drop that came off of some filter floss that is the only one in the tank is effectively zero.

A neat find, but even on the off chance that it was a problematic one.... what recourse do you even have? Easier not to worry about boogeymen and only suspect when you actually see something going wrong - save yourself the stress.
